800818 divided by 42 
We want to figure out the number of times 800818 can be divided by 42.

Moving on to step 1:
8 divided by 42 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 42

Moving on to step 2:
When dividing 80 by 42, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 80 and we're left with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 42

Advancing to step 3:
42 can be fit into 380 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 378 from 380 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 42

Step 4:
42 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 190.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 42

Let's proceed to step 5:
The number 42 fits into 281 6 times, leaving a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 1906.0
The remainder is 29 after subtracting 252 from 281.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 42

Going ahead to step 6:
When dividing 298 by 42, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 19067.0
Subtracting 294 from 298 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 19067.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
42 goes into 400 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 19067.09
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
42 can be fit into 220 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19067.095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
42 goes into 100 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 19067.0952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 42, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 19067.09523
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 19067.095238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 19067.095238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 42 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 19067.09523809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 19067.09523809, with a leftover of 2.2e-08.
